Abstract

The objective of this study was to conduct a comparative analysis of anaerobic dynamic membrane bioreactor (AnDMBR) and anaerobic electro-dynamic membrane bioreactor (AnEDMBR) systems. The AnEDMBR systems were operated at two distinct electric field strengths, 0.8 V and 1.2 V. A hydraulic retention time of 5 days was maintained in both systems. A bench-scale continuous flow reactor equipped with a submerged membrane module utilizing activated carbon fabric as the dynamic membrane was employed. Synthetic wastewater with a high chemical oxygen demand (COD) concentration of 11.4 ± 1.0 g/L was used as feed. The AnEDMBR system was equipped with an iron anode and the activated carbon fabric serving as a cathode which used as a dynamic membrane. The results showed that both systems achieved high COD removal efficiency exceeding 98%. Membranes exposed to an electric field of 1.2 V in the AnEDMBR system exhibited better resistance to fouling compared to those exposed to 0.8 V. Scanning electron microscopy (SEM) images of membrane surfaces indicated a positive effect between extracellular polymeric substances (EPS) and the cathodic membrane due to electrostatic repulsion for the applied voltages. This study provides a significant information for the application of AnEDMBR technology in treating of high-COD content wastewater.

厌氧动态膜生物反应器与厌氧电动膜生物反应器系统处理高浓度废水的比较研究

本研究的目的是对厌氧动态膜生物反应器（AnDMBR）和厌氧电动膜生物反应器（AnEDMBR）系统进行比较分析。AnEDMBR系统在0.8 V和1.2 V两种不同的电场强度下工作。两个系统的水力滞留时间均保持在5天。实验采用了一种实验规模的连续流反应器，该反应器配备了浸没式膜模块，采用活性炭织物作为动态膜。以化学需氧量（COD）浓度为11.4±1.0 g/L的合成废水为饲料。AnEDMBR系统采用铁阳极，活性炭织物作为动态膜作为阴极。结果表明，两种系统的COD去除率均达到98%以上。在AnEDMBR系统中，暴露在1.2 V电场下的膜比暴露在0.8 V电场下的膜具有更好的抗污染能力。膜表面的扫描电镜（SEM）图像表明，由于外加电压的静电斥力，细胞外聚合物（EPS）与阴极膜之间存在正作用。本研究为AnEDMBR技术在高cod废水处理中的应用提供了有意义的信息。
